A fellow tank in my guild are at a disagreement about these two trinkets and which is truly superior over the other.
At the moment, it is a comparison between the Heroic Unidentifiable Organ vs. the normal Petrified Twilight Scale.
I favor IO. He favors PTS.
My argument is that IO has more uptime, and armor and stacking stamina is better than armor and a dodge proc.
Interested in what Tankspot thinks about this.
